Nart Posted April 29, 2018 Report Share Posted April 29, 2018 hi , Im trying to log my cylinder pressure during ignition and how my tune if effecting the ignition pressure i have connected an analog in cylinder pizo sensor with 0-5v output connected to my link analog input and i have set the calibration table as provided by the manufacturer till 2000r pm the pressure is shown and it seems logical but after 2000 rpm it 0 any ideas on how to log the in cylinder pressor til 7000 rpm thanks Quote Link to comment Share on other sites More sharing options...
Steve Posted April 29, 2018 Report Share Posted April 29, 2018 You dont have the logging rate for this sort of stuff. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 30, 2018 Report Share Posted April 30, 2018 Although I agree with Steve's comment that you are not likely going to get anything useful from logging a cyl pressure transducer that is not referenced to engine position, I still dont see any reason why you cant log it. Since you say it reports zero after 2000RPM, I suspect maybe your error low/high fault settings are tripping? Quote Link to comment Share on other sites More sharing options...
Nart Posted April 30, 2018 Author Report Share Posted April 30, 2018 Thank you guys , I agree its the it could be the rate ,but do u have a suggestion to make it work ,maybe there is s module that would calculate it ,,, 1 hour ago, Adamw said: Although I agree with Steve's comment that you are not likely going to get anything useful from logging a cyl pressure transducer that is not referenced to engine position, I still dont see any reason why you cant log it.

Adamw , Im using it to monitor the changes in the cylinder also its really useful for ignition mapping ,as im a part of a team here in jordan working on a new engine tecnology as we are monitring the combustion before and after using link ecu Quote Link to comment Share on other sites More sharing options...
